Abstract
The utility model relates to a combined-type lower crossbeam of a forging hydraulic machine, which relates to a lower crossbeam of a large-sized forging hydraulic machine, and solves technical problem that an integral lower crossbeam forge piece is difficult to pour. The combined-type lower crossbeam comprises a middle lower crossbeam and two side lower crossbeams, wherein the two side lower crossbeams are arranged on two sides of the middle lower crossbeam, the side surface of each side lower crossbeam, which is contacted with the middle lower crossbeam, is respectively provided with a key, two side surfaces of the middle lower crossbeam are respectively provided with a wedge key, the side surface of the middle lower crossbeam is attached to the side surface of each side lower crossbeam, and the side surface of the middle lower crossbeam are connected with the two side lower crossbeams through a plurality of groups of studs and nuts. The combined-type lower crossbeam has advantages of simpleness in structure, reliability in use and good manufacturability.
Description
Technical field
The utility model relates to hydraulic press, particularly a kind of sill of large-sized forging hydraulic press.
Background technology
Along with developing rapidly of the industries such as electric power, iron and steel, petrochemical industry, weapons, market increases rapidly the demand of large forgings, requires hydraulic forging press to have higher pressure and larger size.
Sill is a critical piece of hydraulic forging press, and it bears whole pressure, and the top devices such as travelling table of also will installing.Generally, sill adopts casting structure.Along with the increase of press specification, the size of sill and weight are also increasing.Such heavy parts has brought very large difficulty for smelting, casting technique.For example the sill pts wt of 125MN hydraulic forging press needs about 650 tons of molten steel up to 400 tons, if adopt overall structure, not only cast is very difficult, and is difficult to guarantee casting quality.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of hydraulic forging press combined lower crossbeam is provided, and solves the technical problem of whole sill casting pouring difficulty.
The utility model is achieved through the following technical solutions:
A kind of hydraulic forging press combined lower crossbeam, it is characterized in that: described combined lower crossbeam comprises: a middle sill, two side sills, two described side sills are arranged on the both sides of described middle sill, two side difference fitting keies that described side sill contacts with described middle sill, wedge key is installed respectively in two sides of described middle sill, and the side of the side of described middle sill and described side sill fits, and connects with some groups of double-screw bolts, nut.
Described center stud has the through hole that can place heating tube.
Described key is fixed on the described side sill by the I screw; Described wedge key is fixed on the middle sill by the II screw.
The utility model compared with prior art owing to change whole sill foundry goods into three assembly foundry goods, has reduced the molten steel consumption of once-cast, so that large-scale, ultra-large type sill is achieved manufacturing, thereby hydraulic forging press is developed to more specifications; Owing to be provided with positioning key at combinatorial surface, between combinatorial surface, connect with some groups of double-screw bolts, nut, guaranteed that the bulk strength of fabricated structure and rigidity are not less than monolithic construction; The utlity model has simple in structure, use reliable, the advantage that anufacturability is good.
Description of drawings
Fig. 1 is structural representation of the present utility model (A-A cutaway view).
Fig. 2 is the top view of Fig. 1.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, a kind of hydraulic forging press combined lower crossbeam, comprise: a middle sill 1, two side sills 2, two described side sills 2 are arranged on the both sides of described middle sill 1, two side difference fitting keies 4 that described side sill 2 contacts with described middle sill 1, and wedge key 6 is installed respectively in 1 two sides of described middle sill, the side of the side of described middle sill 1 and described side sill 2 fits, and connects with some groups of double-screw bolts 8, nut 9.
Described double-screw bolt 8 centers have the through hole that can place heating tube.Heating tube is with double-screw bolt heating, elongation, and again with fastening nuts, after the cooling, double-screw bolt has certain stress, realizes the prestressing force pretension.
Described key 4 is fixed on the described side sill 2 by I screw 5, and being screwed can be locking.The location that middle sill 1 and side sill 2 are realized sill horizontal width direction (Y-direction) by key 4.
Described wedge key 6 is fixed on the middle sill 1 by II screw 7, and wedge key 6 is fixed on the middle sill 1 by screw 7, and being screwed can be locking.The location that middle sill 1 and side sill 2 are realized sill short transverse (Z direction) by wedge key 6.
The side 1.1 of described middle sill 1 and side 1.2 fit with side 2.1 and the side 2.2 of side sill 2 respectively, realize the location of sill horizontal length direction (directions X),
